Download and install Eagle

Designing circuits with Eagle

Open Eagle

  • Select New Project
  • Select New Schematic

Open library turn off all libraries, right click use none: scroll down to supply enable

  • fab.lbr
  • supply1.lbr
  • rcl.lbr
  • led.lbr
  • v-reg.lbr
  • Open library, click Use
  • Download from the internet a library or select on in the computer the library that we will be using (e.g.
  • fab.lbr[1]
  • SelectAdd, then you can open the library
    • (if you don't find your thing you could also click on "Use")


Tour for the Eagle on CadSoft site


  • Select the things you want to use and click Add to get the components.
  • You can select different view by clicking on Board
  • You can select object by rightclicking them and selecting packning
  • Connect objecs by clicking Wire and make wire between objects.
  • It can be good to make connections and get a sign for Ground and put where it should be GND.
  • View Grid select the size of the grid, it should be around (0,025 inches)
  • Move to move object or line.
  • Delete to remove object or line and so on.
  • Junction Connection point .
    • You can right click objects and select value to set values e.g. for capacitors or resistors
    • Right click on object and select properties to rename.
    • You can check out if you have connected the object by moving them.
  • ERC Error correction, search for errors.

Arrange objects

Add

  • Frame to make frame around the design.
  • Arrange objects
  • click Auto
    • Select Bottom N/A

If it is not as good as you wanted you can select lines, by right clicking them and select rip off


Info about Circuits

  • TX transmit
  • DTR data terminal ready
  • Rx Recieve
  • Miso -master in slave out
  • Mosi master out slave in
  • sck system clock
  • MOSI (3) GND (2) MISO (1) |
  • -RESET (4) SCK (5)

Project 1

  • First project could be to make schematic of this board and to add something to it, add (at least) a button and LED (with current-limiting resistor) to the serial echo hello-world board, check the design rules, and make it

Materials used

  • IC1 = ATtiny44_SOIC('IC1\nt44') -> see in atmel-new.lbr
  • R1 = R_1206('R1\n10k') -> See in ng.lbr
  • C1 = C_1206('C1\n1uF') -> sparkfun.lbr
  • XTAL = Crystal 20 MHz -> search for crystal in ng.lbr
  • FTDI connector (6 pin) ->search for ftdi in ng.lbr
  • Header (2*3 pin) -> search for isp in sparkfun.lbr
